IMPROVEMENT IN WAGON-JACKS.

Specification forming part of Letters Patent No. 206,516, dated July 30,1878; application filed July 10, 1878.

To all whom it may concern Be it known that I, J OSEPI-I J. ADGATE, ofNew York, in the county of New York, and in the State of New York, haveinvented certain new and useful Improvements in IVagon- J acks; and dohereby declare that the followingis afull, clear, and exact descriptionthereof, referencebein g had to the accompanying drawings, and to theletters of reference marked thereon, making a part of thisspecification.

The nature of my invention consists in the peculiar construction ofjacks for lifting wagon-axles and for other purposes, as will behereinafter more fully described.

To enable those skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

In the accompanying drawings, making a part of this specification,Figure 1 represents a perspective view of lny improvement, and Figs. 2and S detached portions.

Inthe figures, A represents a standard, which may either be made oftriangular or T- shaped malleable iron. On the bottom of this standardis a foot-piece, I The upper portion of the standard A is provided witha series of upwardly-proj ectin g hooks or arms, 0.

D represents a bar, which is provided with a series ofdownwardly-projecting hooks or arms, 0; said bar being parallel with thestandard A and its hooks. The bar D is sit uated a short distance fromthe standard A, and is connected to it by the cross-pieces 1 and G, andby the brace II and cross-bars yy. The parts mentioned are all cast inone piece, and then made malleable.

Cast upon the standard are two wings, z 'i, which project straight fromthe standard when cast, but which are afterward bent as represented inthe figures, so that they will act as a keeper for the lever which isused when it is not in use.

J represents the lever. This is simply a detached iron rod, which has acurve at a, and another at d. The curve at a lies in upon the hooks at c0, while the axle to be raised lies in the curve d.

In operating this jack, the lever J has its curve a placed upon one ofthe hooks c, in accordance with the height of the axle of the vehicle.The curve (Z is placed under the axle, and then the outer end of thelever is pressed down until the axle is lifted so that the wheel doesnot touch. the ground. It is then caught under one of the hooks e, andthus keeps the axle suspended. The entire body of the jack being made ofmalleable iron, it can be made very light, as also strong and cheap.

IV hen the lever is not in use it is placed in the loop formed by thewings i 5, and is thus snugly packed away for future use.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The jack herein described, cast of one piece of metal, consisting ofthe standard A, provided with upturned teeth or hooks c, and the bar D,connected as represented, and provided with the downwardly-projectingteeth or hooks e, and the braces F G and g y, as and for the purpose setforth.

2. In combination with the body of a jack, constructed substantially asherein described, the lever J, provided with the curves (1 and d, as andfor the purpose specified.

In testimony that I claim the foregoing I have hereunto set'my hand this9th day-of July, 1878.

J. J. ADGATE.
